Numbers engaged and casualties
are difficult to accurately establish. Fortunately, for the Federals
an official report of casualties for each Unit engaged was made out
on May 22, 1864, but somehow it never found its way into the Official
Records, nor is it to be found in the National Archives. However, the
New York Tribune published it in full on May 27, 1864, and this is
the source of most of the Federal figures below.

Confederate losses are more
difficult to come by, though a few scattered reports exist, For the purposes
of this list, only casualties of those units engaged in the main battle
are listed; losses suffered before or after that are not included. Information
adopted from The Battle of New Market by William C. Davis
